FRANK GUNN FARNHAM, OF HONESDALE, PENNSYLVANIA.

DEVICE FOR MANIPULATING CUT-GLASS ARTICLES.

To all whom it may concern:

Be it known that I, FRANK GUNN FARN- HAM, a citizen of the United States, residing at Honesdale, Pennsylvania, have invented certain new and useful Improvements in Devices for Manipulating CuteG'lass Articles, of which the following is a specification.

My present invention relates to improved means or apparatus for handling or manipulating cut glass articles during the finishing process when it is desired to subject the cut surfaces to the action of an acid bath.

In applications filed by me in the United States Patent Office on the 3rd day of Feb. and the 1st day of May 1905, and numbered respectively 2.44047 and 258273, I have disclosed levices of this character in which the glass articlesl are supported by carriers pro vided with rubber` plugs which project w ithin and close the mouths of the articles to keep the acid from contact with the interior thereof. In the one case the articles are held pressed against the plugs by pneumatic means and in the other by a follower.

There are certain classes of smaller articles which have almost vertical walls with a slight flare at the mouth. such for instance as wine glasses, tumble-rs of different size and the like. Articles of this nature may be pressed sufficiently' tight upon the rubber plugs of the carriers to enable them to be held thereon by friction without other holding means.

The object of the present invention, therefore, is to provide an extremely simple, and economical device for dipping articles of this nature.

The invention, therefore, includes a support or carrier and a plurality of interchangeable rubber plugs detachably connected to said carrier.

The invention further includes the various features of construction hereinafter described and particularly pointed out in the appended claims.

The invention is illustrated in the accompanying drawings, in Which,-

Figure l. is a central vertical section. Fig. 2 a plan view. Fig. 3 a. bottom view of the base. Fig. 4 a detail view. Fig. 5 is a modification. Fig. 6 a plan View thereof. Fig. 7 a bottom view of the base. Fig. 8 a detail view.

Referring by reference characters to these figures, 6 designates a. carrier or bed plate of Specification of Letters Patent. Application led January 23, 1906, Serial No. 297,504. Renewed March 31, 1908.

suitable acid resisting material, preferably of hard rubber', the bottom of which is strengthened by the annular ribs 7 and 8 and radial ribs `9. A standard 1() projects upwardly from the center of the base and this may be in the form of a metal rod having its lower end screwed into a threaded open ing in the base plate as shown at 1l. It is surrounded by a tubular rubber sleeve 12, serving to protect it from the acid, the sleeve 12 being held in place by the handle 13 threaded upon the upper end of the rod serv ing as a lifting device. Any number of plugs may be used according to the shape and size of the device and the number of articles it is required to dip at one time. Each of these plugs comprises a core 14 held to the base by a screw l5 passing through the center of same and engaging a threaded opening in the base plate. Over this core is stretched a soft rubber cover 1G which is molded tothe desired shape. While the friction of the rubber upon the core will ordinarily be sufficient to hold it against displacement, I lnay provide the cover 16 with an inwardly extending flange 17 clamped between the base of the core and bed plate. The core 14; I prefer to make from wood on account of its light weight and cheap construction, but other material may be substituted, for instance a core cast from aluminum and made hollow as shown in Fig. Ll. When an article having a slightly flaring mouth is pressed tightly upon one of these plugs the soft rubber cover adapts itself to any slight inequalities in the surface of the glass and elfectually excludes the acid from entering the interior of the article while the frictional contact will prevent the article from slipping olf the plug when it is being submerged in the acid bath. When tumblers or like articles of different size or slightly different shape are to be dipped, the plugs can be readily removed and new plugs substituted.

While in Fig. l. l have shown a device with a standard and handle placed in the ceiiter for handling six tumblers, and while it will handle six smaller pieces and more, larger pieces could not be dipped on account of the standard 10`interferin with them. I have shown in Fig. 5 a modification of the device wherewith Without materially in creasing either the size or cost, nine similar sized articles may be dipped. rlhe bed 18 in this case I make practically square with rounded corners` and instead of distributing the plugs` in a circle as in the other circular shape, l place them in rows of three each or nine in all. I employ two standards l9 19 instead of one, which are screwed into the tlange of the base plate at two corners, leaving the whole Central space open. A crosS bar 2() with a handle 21 is connected to the two Standards by means of the elbow unions Q2 into which the three pieces are threaded.

This acts as a handle to lift and manipulate the device. I have shown a plug 24 with its rubber cover 23 secured in position by screw 25 on the right ready to receive a tumbler and in the middle a sectional elevation of the tumbler Q6 and plug and on the left the same :u: it will appeal' when ready for dipping. A plan view of the upper face of the bed is Lshown in Fig. 6 with nine plugs as they could be arrangjec'l, and in Fig. 7 I show a bottom view of the device, the ribs preventing undue wear to the bed plate without materially adding either to its cost or weight.

Having thus deecribed muv invention what I claim iszl. A portable device for dipping glass articles, having open mouths, in an acid bath comprising a supporting member having` a suitable handle and a plurality ot' tapered plugs carried by said supporting member and having elastic surfaces, substantially aa described.

2. A portable device for diplfiing glass article@ having' open mouths in an acid bath comprising a Sulpiporting member having a Suitable handle. and removable and interchangeable tapered pluge with 1n x,ans for de taehal'ily connecting them to the supporting' plate, substantially as described.

3. A device for dipping eut glass articles` in an acid bath comprieinga supirorting plate, a Suitable handle therefor, a plurality of plugs, means for detachably connectingl the plugs to the plate and rubber covers for said plugs, substantially as described.

4. A device for dipping` eut glaes articles in an acid bath comprising a supporting' plate, a plurality of removable and iuterchangeable plugs, screws passing through the plugs and securing them to the support` ing' plate, and a rubber cover for each plug having.,T an inwardly extending1 flange to be clamped between the plug' and plate and an opening' in the upper end to permit access to the screw, substantially as described.

In testimonlxT whereof I aflix my signature in presence of two witnesses.
